[SERIAL] 8250: add locking to console write function
x86 SMP breaks as a result of the previous change, we have no real option other than to add locking to the 8250 console write function. If an oops is in progress, try to acquire the lock. If we fail to do so, continue anyway. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
